Is there anybody in the Obama Administration who can read this and then advocate for letting these arrogant war criminals off the hook for their betrayal of the concept of humanity and their shredding of the Constitution? If so, they will have become one and the same.

United States interrogators killed nearly four dozen detainees during or after their interrogations, according a report published by a human rights researcher based on a Human Rights First report and followup investigations.

In all, 98 detainees have died while in US hands. Thirty-four homicides have been identified, with at least eight detainees — and as many as 12 — having been tortured to death, according to a 2006 Human Rights First report that underwrites the researcher’s posting. The causes of 48 more deaths remain uncertain.

The researcher, John Sifton, worked for five years for Human Rights Watch. In a posting Tuesday, he documents myriad cases of detainees who died at the hands of their US interrogators. Some of the instances he cites are graphic.

Most of those taken captive were killed in Afghanistan and Iraq. They include at least one Afghani soldier, Jamal Naseer, who was mistakenly arrested in 2004. “Those arrested with Naseer later said that during interrogations U.S. personnel punched and kicked them, hung them upside down, and hit them with sticks or cables,” Sifton writes. “Some said they were doused with cold water and forced to lie in the snow. Nasser collapsed about two weeks after the arrest, complaining of stomach pain, probably an internal hemorrhage.”

Another Afghan killing occurred in 2002. Mohammad Sayari was killed by four U.S. servicemembers after being detained for allegedly “following their movements.” A Pentagon document obtained by the American Civil Liberties Union in 2005 said that the Defense Department found a captain and three sergeants had “murdered” Sayari, but the section dealing with the department’s probe was redacted.

Perhaps the most macabre case occurred in Iraq, which was documented in a Human Rights First report in 2006.

“Nagem Sadoon Hatab… a 52-year-old Iraqi, was killed while in U.S. custody at a holding camp close to Nasiriyah,” the group wrote. “Although a U.S. Army medical examiner found that Hatab had died of strangulation, the evidence that would have been required to secure accountability for his death – Hatab’s body – was rendered unusable in court. Hatab’s internal organs were left exposed on an airport tarmac for hours; in the blistering Baghdad heat, the organs were destroyed; the throat bone that would have supported the Army medical examiner’s findings of strangulation was never found.”

In another graphic instance, a former Iraqi general was beaten by US forces and suffocated to death. The military officer charged in the death was given just 60 days house arrest.

“Abed Hamed Mowhoush [was] a former Iraqi general beaten over days by U.S. Army, CIA and other non-military forces, stuffed into a sleeping bag, wrapped with electrical cord, and suffocated to death,” Human Rights First writes. “In the recently concluded trial of a low-level military officer charged in Mowhoush’s death, the officer received a written reprimand, a fine, and 60 days with his movements limited to his work, home, and church.”

Another Iraqi man was killed in a US detention facility on Mosul in 2003.

“U.S. military personnel who examined Kenami when he first arrived at the facility determined that he had no preexisting medical conditions,” the rights group writes. “Once in custody, as a disciplinary measure for talking, Kenami was forced to perform extreme amounts of exercise—a technique used across Afghanistan and Iraq. Then his hands were bound behind his back with plastic handcuffs, he was hooded, and forced to lie in an overcrowded cell. Kenami was found dead the morning after his arrest, still bound and hooded. No autopsy was conducted; no official cause of death was determined. After the Abu Ghraib scandal, a review of Kenami’s death was launched, and Army reviewers criticized the initial criminal investigation for failing to conduct an autopsy; interview interrogators, medics, or detainees present at the scene of the death; and collect physical evidence. To date, however, the Army has taken no known action in the case.”

Death from interrogation is hard to separate from simple detainee death while in US custody. But one particular case stands out that seems to have fallen by the wayside — the murder of CIA “ghost” detainee named Manadel al-Jamadi, who was tortured to death by a CIA team at Abu Ghraib in 2003.

“Pictures of Abu Ghraib guards Charles Graner and Sabrina Harman posing with al-Jamadi’s dead body, the so-called Ice Man, were among the most notorious of the Abu Ghraib photographs published in April 2004,” Sifton notes. “A CIA officer named Mark Swanner and an interpreter led the team that interrogated al-Jamadi. Nine Navy personnel were also implicated. An autopsy conducted by the U.S. military five days after al-Jamadi’s death found that the cause: “blunt force injuries complicated by compromised respiration.”

“Reporting by The New Yorker’s Jane Mayer and NPR’s John McChesney revealed that al-Jamadi was strung up from handcuffs behind his back, a torture tactic sometimes called a ‘Palestinian hanging,’” he adds. “After an investigation, the CIA referred the case to the Department of Justice for possible criminal prosecution of the CIA personnel involved, but no charges were ever brought. Prosecutors accused 10 Navy personnel of the crime; nine were given nonjudicial punishments, such as rank reductions and letters of reprimand, and a 10th was acquitted.”

Additionally, Sifton notes the CIA may have had some close calls with detainees nearly dying during interrogations: the May 10, 2005, Bush Administration torture memo by Stephen Bradbury notes that doctors were nearby to perform a tracheotomy if during waterboarding the suspect is approaching death.

“Most seriously, for reasons of physical fatigue of psychological resignation, the subject may simply give up, allowing excessive filling of the airways and loss of consciousness,” Bradbury wrote. “An unresponsive subject should be righted immediately, and the integrator should deliver a sub-xyphoid thrust to expel the water. If this fails to restore normal breathing, aggressive medical intervention is required….’”

The memo says CIA doctors were on hand with necessary equipment to perform a tracheotomy if necessary during waterboarding sessions: “[W]e are informed that the necessary emergency medical equipment is always present—although not visible to the detainee—during any application of the waterboard.”
